Momentum

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

How is momentum calculated?

Back

Momentum (p) is calculated using the formula p = mv, where m is the mass of the object and v is its velocity.

Front

What happens to momentum when mass is doubled?

Back

If the mass of an object is doubled, its momentum also doubles, assuming velocity remains constant.

Front

What happens to momentum when speed is doubled?

Back

If the speed of an object is doubled, its momentum also doubles, assuming mass remains constant.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

Is momentum a scalar or vector quantity?

Back

Momentum is a vector quantity, meaning it has both magnitude and direction.

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg·m/s).

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

How does momentum relate to collisions?

Back

In collisions, the total momentum of the system before the collision is equal to the total momentum after the collision, assuming no external forces act on it.

Front

What is an elastic collision?

Back

An elastic collision is one in which both momentum and kinetic energy are conserved.
